You can install a rooflight under your Permitted Development rights as long as it does not project more than 15cm from the roof slope. If the rooflight extends forward of the roof plane on the elevation fronting a highway then it’s not allowed under Permitted Development. If you live in a conservation area, then you may be required to install conservation rooflights, but it’s always best to check with your local authority before you begin.

Kitchens and rooms with lots of direct light benefit from ventilated systems. Rooflights with trickle vents allow a small amount of air movement. Opening rooflights with manual or electric controls give you more flexible ventilation options and can be fitted with opening sashes, climate control and rain sensors. Little and often is our advice when ensuring your home is well-ventilated; windows with trickle vents allow fresh air flow in a room and keep moisture build up to a minimum. Our technical surveyor will evaluate ventilation requirements for your space as part of drawing up your specifications.

If your glass roof or rooflight is south-facing, you may want to upgrade to glass with a solar-control coating. There are many types of solar control coatings, and the darker tint options may help protect your interior finishes, but it does sacrifice the amount of natural light you will get. ODC recommends using a colour neutral coating which effectively looks like “normal” glass. However, this can reduce heat gain by up to 65% which will reduce the need for air-conditioning. This is obviously great for money saving as well as the planet.

Yes, they are designed for your space. The ODC systems offer a choice of sightlines and panel sizes, and once you’ve decided the look and number of panels, the type of threshold, handles and frame colour for your doors and windows, they are manufactured at our production facility in Poole. We have a technical team to design exactly what you want – and to liaise with your architect to ensure your glazing delivers the aesthetic, security and performance you’re looking for.
